I don't think so. When I found out I was pregnant with my 2nd baby here is what happened. I had a pretty good idea that I wad pregnant. So I went in for a test at the doc's office and I knew that I had been having some discomfort when I pee'd. But just thought maybe I was waiting too long to pee. I took the urinalysis at the lab and when my doc told me my preg. test was positive she also said I had a urinary tract infection and gave me treatment for it. I had a healthy baby boy 7 1/2 months later.
